BICYCLE SAFEGUA RD AND SUPPORT.

SPECIFICATION forming part of Letters Patent No. 531,016, dated December18, 1894.

Application filed January 30, 1894. Serial No. 498,493. (No model.) i

To all whom it may concern: 7

Be it known that 1, Tires LUORETIUS Bis- SELL, a citizen of the UnitedStates, residing at Charleston, in the county of Charleston and State ofSouth Carolina, have invented certain new and useful Improvements inBicycle Safeguards and Supports; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to theletters of reference marked thereon,which form a part of thisspecification.

My invention has relation to improvements in bicycles, and consists inan improved mechanical contrivance by which two side arms (e) bearingwheels may be thrown forward until they reach the ground, one on eachside of the driving wheel, thus enabling the rider to steady his machinewhile in motion, or to hold the same while the machine is standingstill. By this attachment the rider may get on and off the machine withsafety. He may start hismachine while the two side wheels are on theground, and after it begins to move, said side wheels may be thrown backout of the way. By the use of said side wheels he may move as slowly ashe pleases or stop entirely and yet have his machine stand erect. 7

In the accompanying drawings: Figure 1 is a side elevation of a bicycle,showing my improvement attached thereto. Fig. 2 is a top plan view ofthe same below the line of section 00, at. Fig. 3 is the angle block towhich the arms of the side wheels are pivoted.

My invention is described as follows:

To the bifurcated arm a, in which-the rear wheel I), is journaled aresecured the angle blocks 0. V Said angle blocks are provided with anaxle or fulcrum c, and a'guide 0 The front part d, of said angle blocksis much thicker than its rear part at, which comes nearly to anedge,vand the lower part d of said blocks is much thicker than the upperpart. 01 The arms 6, are pivoted to the fulcrum c, and lie fiat againstthe face of said angle blocks, and thus said arms are caused tostandoutward, at their lower ends, from the wheel some eight or ten inchesmore or less. To the lower endof each of these arms e, is pivoted awheel or caster e. To the lower connecting rod f, of the bicycle is pivoted an elbow lever g, having secured to its front arm across rod g andto each end of said cross rod g, are pivotedarms 9 each of. whichextends backward and terminatesin a loop g through which loops pass thearms e. These loops extend horizontally from the wheel, so as to allowsaid arms e, to spread as they are drawn forward and contract as theyrecede. To the front of the blocks 0, are secured perforated guides h,through the perforations of which work the said arms The horizontal endof said elbow lever g, is provided with a flange z'. Around the socketj, in which the axle of the sprocket wheel j, is secured a coil spring3' the free end of which works under the flange 1', of the elbow leverg, and throws the same up when freed from the lock spring It. The lowerend of said lock spring is secured to the rear connecting rod is, of thebicycle. Said lock spring is provided with a bend or notch in which theflange i, is locked.

The elbow lever g, the spring 9' and the side arms 9 work on the insideof the pedals and do not interfere with their sweep.

The operation of my invention is as follows: When the bicycle is inmotion the arms e, and the wheels 6', lie back close to the wheel, asindicated by the dotted lines Z. When the operator wishes to bring thewheels 6, forward, he puts his foot on the flange 't', and presses thatend of the lever down until it is caught under the lock of the lockspring 70. This brings, and holds the leg in position, as shown in Fig.1, and when in this position it can play backward and forward only aninch or two, thus enabling the rider to remove his feet from the leverg, and continue to opcrate the pedals of the wheel. With his supportinglegs in this position he can move along as slowly as he pleases or standontirely still. When he desires thatthe wheels occupy the position asindicated by the dotted lines I, he throws the lock spring is, with hisfoot out of contact with the elbow lever g, and said lever thus beingfreed the spring 7' throws that end of it up and the lower end back,which pushes the arms e, back on the inclined face of the angle blocks0, until the wheels 6', again occupy the position indicated by thedotted lines Z.

This attachment can be operated by the foot, without at any timestopping the machine, if so desired.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

In combination with a bicycle, substantially as shown and described, thecombination of the angle blocks 0, secured to the bifurcated arm a;guides 0 secured to the lower end of said blocks; guides h, secured tothe front faces of said blocks; arms e, pivoted to said angle blocks andoperating in guides 0 side arms provided at their rear ends with loop 9encircling arms a; said arms passing through guides it, their front endspivoted to the elbow lever g; elbow lever g, pivoted to the connectingrod f; coil spring 3' secured to the socket j, its free end operatingthe horizontal end of lever 9; look spring 70, adapted to lock thehorizontal arm of lever g, substantially as shown and described and forthe purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
